Usage

To use the useScrollLock hook, follow these two steps:

1. Wrap your application with ScrollLockProvider.
2. Use the useScrollLock hook in your component.

Step 1: Wrap your application with ScrollLockProvider

In your main application file (e.g., App.jsx), wrap your application with the ScrollLockProvider component:

// App.jsx
import { ScrollLockProvider } from "@yoojinyoung/usescrolllock";

function App() {
  return (
    <ScrollLockProvider>
      <YourAppComponents />
    </ScrollLockProvider>
  );
}

Step 2: Use useScrollLock in your component

In any component where you want to control the scroll lock, use the useScrollLock hook:

// SomeComponent.jsx
import { useEffect } from "react";
import { useScrollLock } from "@yoojinyoung/usescrolllock";

function SomeComponent() {
  const { lock, release, isScrollLocked } = useScrollLock();

  useEffect(() => {
    const lockerId = lock();

    return () => {
      release(lockerId);
    };
  }, [lock, release]);

  console.log(isScrollLocked); // Check if the scroll is locked

  return <div>{/* Your component content */}</div>;
}

API

The useScrollLock hook provides the following API:

1. lock: (id?: string) => string

• This function locks the scroll and returns a locker ID, which can be used to release this lock.
• It creates a unique ID if you don't pass an ID, but you can use your own ID if desired.

2. release: (id?: string) => void

• This function releases the scroll lock associated with the given locker ID.
• If you do not pass a locker ID, it releases all scroll locks created by this hook.

3. isScrollLocked: boolean

• This boolean value indicates whether the scroll is currently locked or not.
